2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.
Overview

3 Overview
The 910 is a high-performance stereo audio preamplifier. It accepts
balanced and unbalanced stereo audio, S/PDIF digital audio, and
microphone inputs, processes the signals, and outputs the m to balanced,
unbalanced and S/PDIF outputs.
The 910 has the fo l lowing features:
• Grouped audio controls: volume, balance, bass, mid, treble,
loudness, equalizer, delay, mute, expand and compress
• Selectable condenser or dynamic mic input with talk over, mix and
override controls
• A 24-character by 2-line LCD display
• Memory locations that store up to 4 presets to be recalled and
executed when needed
• A USB port for software upgrades
• Flexible control options including the front panel, RS-232 (with
Windows®-based control software included), Ethernet and IR
• Standard 19” rack mount size of 1U with rack "ears" included
To achieve the best performance:
• Use only good quality connection cables
1
• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer 910
away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal q uality due to poor matching, and elevated
noise levels (often associa te d with low quality cables).

Message starting character
'#' – For host command/query
'~' – For machine response
Device address (Optional, for K-NET)
K-NET Device ID followed by '@'
Query sign
'?' follows some commands to define a query request.
All outputs sign
'*' defines all outputs.
Message closing character
CR – For host messages; carriage return (ASCII 13)
CRLF – For machine messages; carriage return (ASCII 13) + line-feed
(ASCII 10)
Command chain separator character
When a message string contains more then one command, a pipe ( '|' )
character separates each command.
Spaces between parameters or command terms are ignored.
10.11 Entering Commands
You can directly enter all commands using a terminal with ASCII
communications software, such as HyperTerminal, Hercules, etc. Connect
the terminal to the serial, Ethernet, or USB port on the Kramer device. To
enter
CR , press the Enter key.
( LF is also sent but is ignored by command parser).
For commands sent from some non-Kramer controllers like Crestron, some
characters require special coding (such as, /X##). Refer to the contro lle r

10.12 Command Forms
Some commands have short name syntax in addition to l ong na me syntax to
allow faster typing. The response i s always in long synt ax.
10.13 Command Chaining
Multiple commands can be chained in the same string. Each command is
delimited by a pipe character ( '|' ). When chaining commands, enter the
message starting character and the message closing character only once,
at the beginning o f the stri ng and at the end.
